Annelida

Annelida, a phylum of segmented worms, ranges in size from 1mm to 3 meters. They possess a fluid outer body with a non-shedding cuticle and a complex nervous system, including a brain and approximately 100 body segments. These worms have unique adaptations, such as using their tails to sense temperature, which helps them decide whether to submerge in water or burrow underground. Annelida play vital roles in ecosystems—earthworms enhance soil quality, while some species are used in medical fields. Explore the diverse and intriguing world of these important organisms!
